Description
On projection displays using laser light sources, speckles are generated by the high coherency of laser light. We have investigated the effect of a small moving diffuser placed at the conjugate point of a micro-display to reduce speckle, and have studied how the optical magnification ratio, the F-number of the projection lens and the diffusing angle range of diffuser affect the speckle reduction ratio.
